Is St. Landry Parish, LA in a flood zone?
FEMA's National Risk Index puts St. Landry Parish's flood hazard at the 87.4th percentile nationally — a middling flood hazard by national standards — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.4 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
